About Drainage Design Management System for Windows, Version 5.3.0

The Drainage Design Management System for Windows (DDMSW) program was initially developed as a pre-processing tool for HEC-1 modeling. In recent years, functionalities of the DDMSW program have been extended to also include Hydraulics and River Mechanics.

The new version of the program (DDMSW 5.3.0) offers much-improved features and capabilities on the three core modules of the program. On the Hydrology module, DDMSW enhances the development of HEC-1 model and the use of Rational Method including post-processing and better precision reporting of model results. On River Mechanics module, the program provides refined procedures in performing scour evaluation, riprap sizing, launch-able riprap design, sediment yield analysis, and lateral erosion investigation.

The new release of the program also offers new tools and improved functionalities of the Storm Drainage Hydraulics module.

New Features of DDMSW 5.3.0

DDMSW 5.3.0 offers a simplified GUI of the program. When a new project is created, users can select which module(s) to use so that the program can only deploy the menu items that are relevant to the module(s) selected. This improvement eliminates unnecessary menu items that are not used by the program. In addition to the GUI enhancement, there are new features and capabilities of DDMSW 5.3.0.

Hydrology

Use of shapefile to assemble routing data for normal depth, kinematic wave, and Muskingum-Cunge.
